Paper-jogger



UNITED STATES PATENT OFFICE.

FRANK A. ONDERDONK, OF GRAND RAPIDS, MICHIGAN.

PAPER-JOGGER.

SPECIFICATION forming part of Letters Patent No. 487,152, dated November 29, 1892.

Application filed June 11, 1892- Serial No. 436.368. (No model.)

To all whom it may concern:

Be it known that I, FRANK A. ONDERDONK, a citizen of the United States, residing at the city of Grand Rapids, in the county of Kent and State of Michigan, haveinvented certain new and useful Improvements in Paper-Joggers, of which the following is aspecification.

This invention relates to a device for straighteni ng and evening up paper of various kinds as it is received from the printingpress; and the same consists in atable or platform for receiving the printed paper and series of perpendicular or nearly-perpendicular jogger-arms supported on vibrating levers, said arms moving substantially in an arc of circles, the whole operated by a stroke of the fingers of the fly which carries the printed paper from the press to the jogger; and the objects of my invention are, first, to produce a cheap and superior jogger having tipping arms for straightening the paper; second, to produce a jogger which can be operated without any direct attachment to the printingpress simply by the shock of the fall of fingers of the fly as it delivers the printed sheet to the jogger-platform. These objects I accomplish by means of the mechanism illustrated in the accompanying drawings, in which Figure 1 shows a plan View of my invention with a portion of the table or platform cut away in order to show the connection of the levers which support the jogger-arms, a portion of the fly of the printing-press being also exhibited. Fig. 2 is a sectional view on lines 2 2 of Fig. 1.

Similar letters refer to similar parts throughout the several views.

A represents the base, constructed in any suitable manner. Upon the base and attached thereto I provide supports, (shown by A5 A, the.) Upon the upper end of these posts is supported the table or platform B. In the example of my invention shown in the drawings I have illustrated two slots on each side of the table, which slots are shown by B. I also provide a central rod or support, (shown by O.) Surrounding the rod 0 is a sleeve D,

adapted to move up and down the rod 0.

The jogger-arms J are adapted to move in the arcs of circles, and they are operated by the sleeve D and a lever mechanism comprising, as here shown, the levers E E, four in number, which are pivoted at their inner extremities to the sleeve D. This lever mech anism is entirely disconnected from the fly of the printing-press, which fly is composed of a series of fingers secured to a bar M in the usual manner. A part of the lever mechanism projects into the path of the free end of the fly, and as here shown this projecting part is composed of a standard K, secured to the lever E and having a cross-bar L, which may be provided with a suitable covering L, the construction being such that in the descent of the fly several fingers thereof will strike the crossbar L, and thereby lift the sleeve D, which causes the jogger-arm J to swing outward in a direction away from the center of the plat form. I prefer to attach two jogger-arms to each lever by means of an adjustable attachment.

J represents the adjustable attachment, which is adjustable under the levers, thereby carrying the jogger-arms J either toward. or away from the center, and a set-screw I is used for holding the attachment J and the arms J in position. The object of the attachment is to adapt the jogger to different-sized sheets of paper. I have also shown a nut I, which may be used for attaching the joggerarms to the jogger attachment J; but this may be dispensed with and the jogger-arms attached in any suitable manner. Instead of using the flat spring shown by F, any suitable means may be employed for depressing the sleeve and raising the jogger-arms.

The printed sheet is placed upon the platform or table when the jogger-arms are open, and as the fly is raised the jogger-arms return to their normal position, and this movement of these jogger-arms carries the sheet to the required position.

As the lever mechanism which operates the jogger-arms is not connected with or attached in any manner to the fly or to the printingpress, the jogger can be moved from one press to another without the necessity of attaching or detaching parts, it only being essential to locate the projecting part of the lever mechanism in the path of the free end of the fly. Having thus described my invention, what I claim to have invented, and desire to secure by Letters Patent, is-

1. The combination,with a supporting-platform and a series of jogger-arms arranged substantially perpendicular and movable in the arcs of circles, of a lever mechanism entirely disconnected from the fly of a printingpress and having a projecting part adapted to be located in the path of the free end. of the said fly, so that when the latter descends it will strike the projecting part of the lever mechanism and operate the jogger-arms, substantially as described.

2. The combination of a supporting-table, a series of levers pivotally attached to a sleeve, fulcrums for said levers, jogger-arms extending upward nearly perpendicular from said levers and adjustably connected therewith, and a trip adapted to receive the stroke of the fly of the printing-press, substantially as described.

3. The combination of a series of levers pivotally attached to a sleeve, a series of joggerarms attached to said levers, fulcrums for supporting said levers, a trip connected with said levers, and a spring adapted to bring the levers and jogger-arms into normal position after the same has been pressed from normal position by means of the fly, substantially as described.

4-. The combination of a platform provided with slots through which the jogger-arms are adapted to pass, jogger-arms extending from beneath upward through said slots, levers supporting said j ogger-arms, a sleeve to which said levers are pivotally attached, and a spring or other suitable means for bringing the arms to a normal position after having been pressed out of normal position by the fly of the printing-press, the whole adapted to be operated by the stroke of the fly or the finger thereof without any other action of or connection with the press, substantially as described.

In witness whereof I have hereunto set my hand and seal in the presence of two Witnesses.

FRANK A. ONDERDONK.
